The Scout sign shows you are a Scout. Give it each time you recite the Scout Oath and Law. When a Scout or Scouter raises the Scout sign, all Scouts should make the sign, too, and come to silent attention.
To give the Scout sign, cover the nail of the little finger of your right hand with your right thumb, then raise your right arm, bent in a 90-degree angle, and hold the three middle fingers of your hand upward. Those fingers stand for the three parts of the Scout Oath. Your thumb and little finger touch to represent the bond that unites Scouts throughout the world.
